ASIR enables big CT dose reductions in the abdomen

By Eric Barnes

Adaptive statistical iterative reconstruction (ASIR) of CT data cuts noise and boosts diagnostic confidence of abdominal lesions while slashing radiation dose, reported researchers who used an ASIR algorithm instead of traditional filtered back projection.

CAD labels abdominal vessels with improved accuracy

By Eric Barnes

A new computer-aided detection (CAD) algorithm automatically labels abdominal arteries extracted from CT images. The work-in-progress system is more accurate and less dependent on error-prone features than previous CAD schemes, say researchers from Nagoya, Japan.

Extracolonic findings add value to VC screening

By Eric Barnes

In a new study of more than 2,000 patients, virtual colonoscopy found nearly as many cancers outside the colon as inside it. This ability to detect serious extracolonic abnormalities is a major benefit of VC screening, researchers report in the September issue of the American Journal of Roentgenology.

Study: Hold the CT for pediatric renal trauma

By AuntMinnie.com staff writers

Physicians often order abdominal CT scans for pediatric patients who have undergone blunt abdominal trauma and have blood in their urine. However, because this procedure has low sensitivity and specificity, not ordering it may be more clinically prudent, according to a report in Urology.

Quantitative image analysis uncovers more living liver donors

By Erik L. Ridley

Quantitative image analysis may be able to significantly increase the number of living liver donors, according to Colorado researchers. Re-evaluation of previously rejected donors with a quantitative image analysis system found that most had suitable anatomy for transplantation.

Perfusion CT finds subtle liver toxicity in chemotherapy patients

By Eric Barnes

A new study from China found that perfusion CT can detect and quantitatively assess microvessel changes associated with liver toxicity in chemotherapy patients. The results could help noninvasively assess early liver damage in cancer patients while obviating the need for a separate scan.

Contrast US processing tool shows malignant liver lesions

By Eric Barnes

Swiss researchers have developed a real-time parametric imaging technique for distinguishing benign from malignant liver lesions easily and noninvasively using contrast-enhanced ultrasound. In its first clinical run, the method delivered high sensitivity and specificity in a patient cohort.

Pancreatic CT pitfalls can be avoided

By Eric Barnes

Evaluating pancreatic CT images to determine resectability is one of the more difficult jobs in radiology, perhaps more so because the stakes are so high. But a lot of mistakes can be avoided with 3D imaging and careful attention to a few details.
